<h1><a name="hid_tab_extra"></a>Extra parameters</h1>
<p>
The <i>Extra</i> tab contains a list of more advanced and specialised settings and configuration parameters, including details about Orbiter's dynamic state propagation, vessel configuration and debugging options. Addon plugins may add their own configuration entries to the list when activated.</p>
<p>It is generally safe for new users to leave all settings in this list at their default values. Advanced users can fine-tune the behaviour of the simulator here.</p>
<p>Click on an item to see a short description of its purpose to the right of the list. Double-clicking, or pressing the Edit button opens the associated configuration dialog.</p>
<p>Documentation for some of the standard entries in the Extra list is provided below. For entries added by 3rd party addon modules see the documentation of the individual modules.</p>
